Timezone Sync
Plan cross-timezone schedules with a shared date and hour window. Add timezones, drag-select a time range, and share the exact setup via URL parameters.
Select the anchor timezone from the small home button in each row.
Timezones
Timezone matrix
Rows are compact: timezone name, anchor button, then hourly cells. Drag on any hour cell to paint a range across all rows.
How it works
Timezone Sync treats the chosen date and selected hours as the source schedule in your reference timezone. Each row shows how that same absolute range maps in other IANA timezones.
The URL is updated as you change settings, so sharing the link restores the same timezones, date, range, and hour format.

All calculations run in your browser. Shared links only include your selected settings in query parameters.
